1. An electrowetting optical device comprising:

  • a chamber comprising a first immiscible liquid and a second immiscible liquid contacting each other at a liquid-liquid interface, wherein the first immiscible liquid is an insulating liquid and the second immiscible liquid is a conducting liquid;

    a first electrode in contact with the second immiscible liquid; and

    a second electrode insulated from the first immiscible liquid and the second immiscible liquid by an insulating layer, wherein the second electrode is formed of a conductive molded polymer material, wherein curvature of the liquid-liquid interface is controllable by application of a voltage between the first electrode and the second electrode, and wherein the conductive molded polymer material has a Water Vapour Transmission below 0.15 g.mm/m2.day.
